Extension Activity on 24th March, 2017.

  • Milk Testing Drive

Milk is the most common source of nutrition which is consumed on daily basis in every household. Adulterants if any, present in the milk can cause considerable damage to liver and kidney. In order to check the milk quality, a milk testing booth was set up in the campus outside the D-Block on 24 March, 2017. Students and faculty members were requested to bring milk raw (unboiled) milk samples (200 ml) consumed daily by them. A total of about 36 milk samples were tested which belonged to both pasteurized milk of regularly used brands like Amul, Lotus, Mother dairy, Gorus, Sarasetc as well as milk sold by local vendors of different areas. Students tested the presence of water, sucrose, starch, ammonium sulphate, acid, soap and formalin in the collected samples and generated report which was given to the participants on 25 March 2017. It was found that approximately 14% of the samples were containing residues of acid and about 6% contained formalin. Excess of water was found in about 20% of the samples. However, the presence of other adulterants was not detected in any of the samples collected.
